fore, is useful over and over again without loss- All other devices for this purpose, with which I am familiar, are objectionable for a number of reasons. For example, they depend upon reverse bending or other distortion of a coupling or connection member which dependence makes for fatigue either immediate or eventual so that there is no assurance that the chime can be used with safety more than once. But, discounting that condition, they all sufier the disadvantage-that they essentially embody parts or elements that are in marked offset relation with the barrel and, hence, constitute a decided menace in that they are likely to catch'onto or foul something and so destroy or impair the eiliciency of the seal.

One object of the invention is to provide a keeper chimewhich is'not subject to conditions making for fatigue in service, and which, there:

of efliciency. Another object is to I provide a keeper chime freefrom fouling propensity. 7 An- .other object is to provide a keeper chime having mated coupling members which operate in substantially flush relation. Anotherobject is to provide means for shrouding the coupled parts and to accomplish this in such way as to preserve the smooth external continuity of the chime. Another object is to provide shrouding meansinthe form ofarunneradaptedtobe positioned over the coupled area and eflective to maintain the parts in the coupled state under substantially flush conditions. Another obiectis to provide means which function asabutments for devices for slidably contracting the chime, and as end-stops for. the runner, and as holders forawireforasignettobeappliedtotherunner as a telltale oftampering and pilferlng.

According to my invention one end of the keeper chime has a; medial wall extension 9' which is marginally notched to provide spaced 5 I lateral tongues II and a forwardly projecting. tongue l'l. The: lateral tongues are somewhat depressed and the frontaltongueis distinguished by an upward inclination. The other 'end of the chime is stamped out, as at l2, in coincidence with 19 the construction Otherwise expressed, it

The runner is of suificient length tully to cover the coupled area and, since it par-' takes of the contour of the chime, practically'insures the smooth external continuity thereof so N that there are no hazardous offsets or projections 25 likely to catch onto'something and impair or destroy the seal.

The lugs ll are useful as abutments for the usual appliances for forcibly contracting the chime and as end-stops for the runner l3. They 30 are also apertm'ed for the passage of a wire l5,

Having described my invention, what I claim as new is: I

1. Akeeper chime comprising a split ring of U-section; one end of the ring having a notched strap extension and the other end of the ring having a complementary slotted area to accu rateLy receive the notched strap extension for lochng the ends of the chime against separation, and a member slidably fitted on the chime and having-a length commensurate with the inter- 50 .locked area of the chime and movable to a posi- .tion to overliesuch interlocked area to prevent camal'oftheparmsaidmemberbeing of minimum thickness to avoid obstructing pro- 2.Akeeperchimeeomprisingasplitringo.'

4. A construction as defined in claim 1', wherein the chime is formed with outstanding lugs to limit the movement or the runner in either direction, said lugs providing means to receive an 1.
